I think there is a type function that is built in which gives the type pf the object.

I am sure there is a much more elegant way of doing this (there always is), but here I go anyway:

[CODE=python]
>>> a = [1, 2, 3, 4, 5]
>>> b = dict()
>>> b['a'] = 1
>>> b['b'] = 2
>>> type(a)
<type 'list'>
>>> type(b) == type([])
False
>>> type(b) == type(dict())
True
>>>
[/CODE]

Here is another way using isinstance():[code=Python]>>> seq = [1,2,3,4,5]
>>> dd = dict(zip(seq, ['a','b','b','d' ,'e']))
>>> isinstance(seq, list)
True
>>> isinstance(dd, dict)
True
>>> isinstance(seq, dict)
False
>>> [/code]

Nice!
See, that is why I participate in threads like this, I get to learn neat little tricks :D
